Description

The lifting gear of automatic plastering machine hopper

Technical field

The utility model belongs to building machinery, specifically a kind of lifting gear that makes the hopper automatic lifting of automatic plastering machine.

Background technology

Existing automatic plastering machine is when smearing metope, the outlet subtend metope of its hopper, ash material in the bucket pushes metope with the ash material under the effect of material toggling rod, the rope that is installed in the hoist engine on the base is walked around the fixed pulley of a top of the trellis and the movable pulley on the hopper, be fixed on the hopper then, start the hoist engine rotating and hopper is risen or decline, the ash material is spread upon on the metope equably, reach the purpose of automatic plastering.The lifting of above-mentioned automatic plastering machine hopper, be by the rope high and low of hoist engine climb around finishing, rope can be not oversize when being used for indoor shorter metope, uses more convenient.When being used to smear outdoor high metope, climb back and forth up and down around rope need longly especially, on the one hand because of the oversize swing easily in use of rope, can related plastering machine vibrations make and smear job insecurity, the quality that influence is plastered a wall; On the other hand, climb back and forth up and down around rope take up space greatly, influence is operation such as dress ash etc. in hopper; Moreover, because having grown himself to produce to swing, damages easily by rope than short rope, change a long rope expense height, increased use cost.

The utility model content

Technical problem to be solved in the utility model is, overcome existing automatic plastering machine and drive the hopper lifting with hoist engine, when smearing high metope, need long especially rope, the influence quality and the inconvenient operation of plastering a wall and rope is fragile, increase the shortcoming of use cost provides a kind of lifting gear that can overcome the automatic plastering machine hopper of above-mentioned shortcoming.

In order to solve the problems referred to above that prior art exists, the utility model is to adopt following technical proposals to realize: the lifting gear of described automatic plastering machine comprises stand and by be attached to the hopper of lifting in the stand on one's body from the roller of installing; The lifting of hopper is to be fixed with tooth bar at its shaft of stand upper edge, and the gear that is connected and is meshed with tooth bar with power is installed on hopper.

Advantage of the present utility model and good effect be, owing to be installed in the gear on the hopper and do not need long rope with the tooth bar transmission of its engagement, do not have the problem of rope swing, and the rack-and-pinion engaged transmission is steady, can guarantee the quality of plastering a wall; The wearing and tearing of gear, tooth bar transmission simultaneously are little, do not need frequent replacing, and maintenance cost is low; Gear, tooth bar transmission take up space little, and be very convenient during operations such as the ash of plastering a wall at dress in hopper.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

Among Fig. 1, the lifting gear of automatic plastering machine comprises stand 4, hopper 10, on the respective side facade of hopper 10 width both sides, be installed with rolling wheel support 10.1 up and down respectively, 3 of last bottom rollers are on rolling wheel support 10.1 (referring to Fig. 2, Fig. 3), and hopper 10 rises or descends by the bar side that last bottom roller 3 is attached to the stand of using as guide rail 4; Parallel two the

material toggling rods

1 and 2 that are equipped with along its width in the hopper 10, the bottom of hopper 10 is equipped with motor 9, and drives

material toggling rods

1 and 2 rotations by connected gearbox 8.On the opposite of last bottom roller 3, be vertically fixed with tooth bar 5 on the bar of stand 4 along its shaft; On the hopper 10 edge-on walls on stand 4 right sides, be fixed with support 10.3,10.2 of gear shafts are on support 10.3, one end of gear shaft 10.2 is fixed with driven gear 7, and material toggling rod 2 stretches out on the spindle nose of hopper 10 sidewalls and is fixed with driving gear 11, and driven gear 7 is meshed with driving gear 11; Be meshed with tooth bar 5 with driven gear 7 co-axially fixed gears 6.The upper-lower position of gear shaft 10.2 is between the opposite of bottom roller 3, so that keep stable with respect to stand 4 during hopper 10 work.

When starter motor 9 drives

material toggling rod

1 and 2 rotations, driving gear 11 on material toggling rod 2 spindle noses drives the driven gear 7 that is on hopper 10, by gear shaft 10.2 gear 6 is rotated again, the gear 6 that rotates is smeared metope along tooth bar 5 liftings thereby drive hopper 10 liftings.

Shown in Figure 4 is to be fixed with support 12.1 on the hopper 10 edge-on walls on stand 4 right sides, is fixed with the lifting motor 12 of band gearbox 12.2 on it, also can directly use buncher to replace gearbox 12.2; The output axle head of gearbox 12.2 is equipped with gear 6, gear 6 be meshed with tooth bar 5 on stand 4 shafts (referring to Fig. 5).The output shaft centre-height of gearbox 12.2 and in like manner above-mentioned makes the gear of installing on it 6 between the opposite of last bottom roller 3, keeps stable in the time of just making hopper 10 work.

Start lifting motor 12, rotate by gearbox 12.2 driven gears 6, the gear 6 of rotation is smeared metope along tooth bar 5 liftings thereby drive hopper 10 liftings.The advantage of said structure is, the rotation of the lifting of hopper 10 and material toggling rod 2 comes from two power sources, both do not disturb mutually, can work independently, for example hopper 10 is being fallen when not plastering a wall, the motor 9 that drives the material toggling rod is rotated, but the one side conservation of power also can not dialled the ash material to be sprinkling upon and cause waste on the ground simultaneously because of the rotation of material toggling rod.

Hopper 10 shown in Figure 6 is basic identical with Fig. 1, its difference is that the material toggling rod of installing in it 1 is one, the axle head that stretches out hopper 10 sidewalls at material toggling rod 1 is equipped with drive sprocket 13, driven sprocket 15 is connected with drive sprocket 13 usefulness chains 14, the installation of driven sprocket 15 and Fig. 2 are in the same way, promptly be installed in and be on the axle of the hopper 10 edge-on wall brackets on stand 4 right sides, with driven sprocket 15 co-axially fixed gears 6 and tooth bar 5 engagements.When motor 9 drove 1 rotation of material toggling rod, drive sprocket 13 drives driven sprockets 15 by chain 14 to be changeed, and coaxial gear 6 rolls on tooth bar 5 and makes hopper 10 liftings smear metope simultaneously.

The lifting of the hopper 10 of the two material toggling rods of band also can be adopted the mode of sprocket wheel chain connection transmission as shown in Figure 6.
